【摘要】:土地利用多功能性研究是土地科學(xué)研究的重要內(nèi)容,對(duì)推動(dòng)區(qū)域可持續(xù)發(fā)展具有重要意義。該文以環(huán)京津貧困帶31區(qū)縣為分析單元,構(gòu)建指標(biāo)體系對(duì)該區(qū)2000、2014年土地利用多功能性進(jìn)行綜合測(cè)度,運(yùn)用空間分析方法和空間計(jì)量模型分析其土地利用多功能性時(shí)空分異特征及影響因素。結(jié)果表明,1)2000、2014年環(huán)京津貧困帶土地利用多功能性水平呈現(xiàn)西高東低、中部高南北低的空間格局。2000-2014年土地利用多功能性水平整體有所提升,空間格局變化顯著,主要表現(xiàn)為較高水平區(qū)縣向壩上高原及壩緣山區(qū)擴(kuò)展,中等水平區(qū)縣大幅收縮且略有東移,較低和低水平縣域向市域邊緣地區(qū)集中。2)2000-2014年環(huán)京津貧困帶土地生產(chǎn)功能空間格局變化顯著,主要表現(xiàn)為高水平區(qū)縣向張家口市區(qū)及周邊區(qū)域擴(kuò)展,較高、中等水平區(qū)縣分別呈現(xiàn)北移、東移態(tài)勢(shì),較低、低水平縣域向市域邊緣地區(qū)集中。2000-2014年土地生活功能、生態(tài)功能空間分異格局無(wú)較大變動(dòng),局部地區(qū)略有變化。3)環(huán)京津貧困帶土地利用多功能性時(shí)空分異演化是自然地理環(huán)境、自然資源稟賦、社會(huì)經(jīng)濟(jì)因素和政策因素共同作用的結(jié)果。自然地理環(huán)境、自然資源稟賦是影響土地利用多功能性格局演變的根本因素,而社會(huì)經(jīng)濟(jì)與區(qū)域政策是推動(dòng)土地利用多功能性格局演變的重要因素。
[Abstract]:Multi-functional land use research is an important part of land science research, which is of great significance to promote regional sustainable development. In this paper, 31 counties in the poverty zone around Beijing and Tianjin are taken as analysis units. The index system was constructed to measure the multifunction of land use in 2000 and 2014. The spatial analysis method and spatial econometric model were used to analyze the spatial and temporal differentiation characteristics of land use and its influencing factors. In 2014, the multifunctional level of land use in the poverty zone around Beijing and Tianjin showed a low level in the west, high in the east, and low in the north and south in the middle. The multifunctional level of land use increased from 2000 to 2014. The spatial pattern change is remarkable, mainly for the higher level counties extending to the Bashang plateau and the mountain areas of the dam edge, and the middle level counties shrink sharply and move eastward slightly. The spatial pattern of land production function in the poverty zone around Beijing and Tianjin changed significantly from 2000 to 2014. The main performance is the expansion of high level counties to Zhangjiakou urban area and its surrounding areas, high, middle level counties are moving northward and eastward respectively, and the trend is lower. The land life function of the low level county area from 2000 to 2014 is concentrated to the fringe area of the city area, and the spatial differentiation pattern of the ecological function has not changed greatly. Local area slightly changed. 3) the land use multifunctional space-time differentiation evolution in the poverty zone around Beijing and Tianjin is the natural geographical environment and natural resource endowment. The natural geographical environment and natural resource endowment are the basic factors that affect the evolution of the multifunctional pattern of land use. Social economy and regional policy are important factors to promote the evolution of land use multi-functional pattern.
